FUNCTION up and FUNCTION down keys
These two keys allow for the selection of the setup function. A function summary table is found at the
start of the relevant SETUP, COMMISSIONING or CALIBRATION mode chapter.
OPTION up and OPTION down keys
These two keys allow for changing the option for the selected function. A list/range of options for
each function is found in the function summary table at the start of the relevant SETUP,
COMMISSIONING or CALIBRATION mode chapter.
ENTER key
The ENTER key sets the currently displayed option and stores the value in non‐volatile memory to be
retrieved on device start up. If the ENTER key is not pressed when a new option is chosen, the
previous option will be retained.
Probe impedance key
When this key is pressed the transmitter will measure the impedance of oxygen sensor(s) attached to
the transmitter. If the burner is not enabled (terminals 10 & 11) or the probe temperature is below
700°C (1292°F) impedance checking will not be performed. A ‘Z’ will be seen in the bottom left hand
corner of the display as the test is performed.
Auto calibrate key
When this key is pressed the transmitter will calibrate the analogue output channels that are set to
auto calibration (see chapter 10). This is performed by directing the output current away from the
output terminals (terminals 12&13 and 14&15) back to an analogue input to the transmitter in order
to calculate a zero and span calibration factor for each of the output channels.
During this process normal output to the analogue channels will be interrupted sending the outputs to
zero mA.
